<div class="method">
    <code class="details" id="generateAccessToken">generateAccessToken(name, body=None, x__xgafv=None)</code>
  <pre>Generates an OAuth 2.0 access token for a service account.

Args:
  name: string, Required. The resource name of the service account for which the credentials are requested, in the following format: `projects/-/serviceAccounts/{ACCOUNT_EMAIL_OR_UNIQUEID}`. The `-` wildcard character is required; replacing it with a project ID is invalid. (required)
  body: object, The request body.
    The object takes the form of:

{
  &quot;delegates&quot;: [ # The sequence of service accounts in a delegation chain. This field is required for [delegated requests](https://cloud.google.com/iam/help/credentials/delegated-request). For [direct requests](https://cloud.google.com/iam/help/credentials/direct-request), which are more common, do not specify this field. Each service account must be granted the `roles/iam.serviceAccountTokenCreator` role on its next service account in the chain. The last service account in the chain must be granted the `roles/iam.serviceAccountTokenCreator` role on the service account that is specified in the `name` field of the request. The delegates must have the following format: `projects/-/serviceAccounts/{ACCOUNT_EMAIL_OR_UNIQUEID}`. The `-` wildcard character is required; replacing it with a project ID is invalid.
    &quot;A String&quot;,
  ],
  &quot;lifetime&quot;: &quot;A String&quot;, # The desired lifetime duration of the access token in seconds. By default, the maximum allowed value is 1 hour. To set a lifetime of up to 12 hours, you can add the service account as an allowed value in an Organization Policy that enforces the `constraints/iam.allowServiceAccountCredentialLifetimeExtension` constraint. See detailed instructions at https://cloud.google.com/iam/help/credentials/lifetime If a value is not specified, the token&#x27;s lifetime will be set to a default value of 1 hour.
  &quot;scope&quot;: [ # Required. Code to identify the scopes to be included in the OAuth 2.0 access token. See https://developers.google.com/identity/protocols/googlescopes for more information. At least one value required.
